SPEGIFIOATIN- TO ALL WHOM IT MAY CONCERN:

Be it known that I, GEORGE VINCENT, or Stockton, in the county of SanJoaquin, and State of California, have invented a new and usefulImprovement in Binders for Sewing-Machines; and I do hereby declare thatthe following is a full, clear, and exact description thereof, whichwill enable others skilled in the art to make.

and use the same, reference being had to the accompanying drawingsforming part of this speoication.

My invention relates to an improvement in binders for sewing-machinesand the binder made according to my invention is provided with a plateofv metal with openings, through which moves a-plate so arranged as toform a gauge which can be regulated to suit any width of binding, whilea curve in the plate serves as a guide to the lower edge of the binding.lIt is also provided with a piece of metal so constructed as to form aguide for the upper` edge of the binding, and to turn it over so as togive an equal width to both sides of the binding. It also, by means of ashoulder on its lower side, regulates the distance of the seam from theedge of thebinding, and serves as a guide for its upper edge.

Figure 1 is a top view of the guide for the lower edge of the binding,and the attached Vgauge for regulating it to any width of the binding.

Figure 2 is a side sectional elevation of the same taken through theline 'x z.

Figure 3 is a top view of the guide for the upper edge of the binding.

Figure 4 is a side elevation of the same.

Figure 5 is a front'I elevation of the cloth-plate of a sewing-machine,showing the relative position of the needle, presser-foot, and the partsof the binder.

Figure 6 is a top View of the cloth-plate with the diierent parts intheir respective positions.

Similar letters of reference indicate like parts.

A, Hg. I, is a thin, ilat plate 'of metal bent into a curve at B, as isplainly shown in llig. 2. v' lhis curve serves as a guide to the loweredge of the binding. The central portion of this plate, at C, isslightly raised so as to admit the plate E, which passes under the partC, and through openings in the plate A, to the upper surface at at a.'lhis plate is bent at right angles at the point 1J, and has aprojection at c which is bent over so as to give the binding the right,.direotion The plate A and the plate E have slots, e e, through them,and coinciding so as to allow the set-screw, shown inred in fig. 6, topass through and secure the guide to the cloth-plate, and also to fastenthe movable plate at any desired point, as the binding may be `wide ornarrow. G, figs. 8 and 4, represents the body of the guide for the upperedge of the binding-which is fastened to the presser-i`oot by theset-screw g. H is a small spur projecting from the part Gr, at rightangles, and slightly rounded on the side towards lthe lower guide, so asto allow the binding to move easily under it. The spur I-I is somewhatthinner than the part Gr, so that a shoulder is formed ate', fig. 4,which serves as an inside guide for the edge of the binding. i

In order to show clearly its use, I will now proceed to describe itsoperation, using for this purpose the Florence sewingm`achine, to whichthe binder is tted, although they may be applied to any of the machinesnow in use. i

When it is desired to use the binder, the set-screw on the cloth-plateof the inachine'is passed through the slots e e, in the plate A and theplate E. The guide for the upper edge of the binding is then fastened tothe presser-foot by passing the head of the set-screwg through the slotin the presser-foot, and af er moving ii, down to the narrow part of theslot, xing it firmly, so that the spur I-I projects in the directionrepresented in g. 6. The lower edge of the binding is then inserted intothe curve B and moved along till it reaches the spur H, under which itpasses and is turned over towards the front, so that the upper edge ofthe saine touches the shoulder z'. The plate E is then moved'forwarduntil the curved part, c, comes against the curve in the binding and theunder edge rests against the inside of the curve B, when it is fixed bythe set-screw, which holds it to the cloth-plate. The edge of the clothto be bound is then placed /against the inside curve of the binding andthe needle set in motion. The lower edge of the binding will be pressedinto the curve I3, and the upper edge will be turned over by the spurHxand, as it rests against the shoulder t', will be kept in place, sothat the line of stitching will always be at the same distance fromthe-edge ofl the binding. The sethscrew, g, has a little motion fromside to side in theslot in the presser-foot, s o that theshoulder z'will be nearer or further from the line of the needle, thus causing theseam to be nearer to or further from the edge of the binding.

Among the advantages to be gained by the use of this binder are,rst,.its instant adjustability to any thickness of work, from the'faetthat the guide for the uppei` edge of the binding is attached to thepresserfoot, so as to be entirely distinct from the rest of the binder;second, its great simplicity, especially the plan for the adjustment todifferent Widths of binding, and the easewith whichbinding may be put inand taken out, and, notwithstanding the fact that there is but little toconfine the binding, it never gets out of place; third, the use of theguide, for the upper edge of the binding, as an inside guide for keepingthe seam at an equal distance from the edge of the work.

Having thus described my invention, I claim as new, and desire to secureby Letters Patent- The' combination of the plates A and C with the block(Land its spur H, operating substantially as above deseribed and for thepurpose herein set forth.

The above specification of my invention signed by me this 30th day ofAprii, A. D. 1866.
